It's been down for a day, and may be down for a few more. Looks like "Just build your own Internet" isn't a viable option for internet communists, everyone must learn of their peaceful ways by force.
Trying to get to Saidit redirects you to Saidit's Subreddit, in a sad state of affairs.
EDIT:It's come back up since then. Updates in the link.
I'm always more partial to the idea that they're not bad at it per say, rather they apply the same tactics other internet scammers do and lay out bait that smells so bad they know anyone who takes the first bait is almost certainly too naive to not fall for whatever con comes next, no matter how self-sabotaging it is.
To a degree, I'd agree with that. I'm personally a bit paranoid over the prospect that a few fed teams learned how to blend in. Having others continue bungling the work then serves as an effective way to give us a false sense of security.
Of course, as soon as one suggests engaging a federal crime, it's obvious. It's just creepy to think that people around you might be waiting for a chance to report you.
